“While conducting research probing deep time and the origin of continents, Glassley discovered a further source of fascination: the Arctic wilderness of Greenland. In A Wilder Time, he shares his encounters with unvarnished nature still free—for now—from the corruptions and constructs of human settlement. With openness, clarity, and a keen eye for detail, he weaves adventure, research, astonished awe, and thoughtful reflection into an absorbing account of his sojourns.”
